Railway freight shed car roof system

Abstract

The invention discloses a railway freight shed car top cover system which comprises a top cover arranged at the top of a car body and end plates in sealing contact with the front end and the rear end of the top cover, the top cover comprises a fixed cover plate with the hollow middle and two movable cover plates arranged in the middle of the fixed cover plate, and transmission systems are independently arranged on the two movable cover plates; each transmission system comprises a driving structure arranged in the vehicle body, a transmission structure connected with the output end of the driving structure and a connecting rod structure connected with the output end of the transmission structure, and the connecting rod structure is connected with the bottom of the movable cover plate on the same side; the driving structure is used for driving the transmission structure to enable the two movable cover plates to laterally slide in opposite directions through the connecting rod structure so as to open the top cover. According to the invention, the movable cover plate is divided into two parts and is designed into a split sideslip type, the two symmetrical movable cover plates are respectively controlled by two sets of same and independent transmission systems, and the two sets of transmission systems are independent and do not interfere with each other, so that the complexity of a mechanical structure and a transmission mechanism is reduced.

Description

technical field [0001] The invention relates to the field of railway freight equipment, in particular to a top cover system for a railway freight box car. Background technique [0002] A boxcar for railway freight transport is a vehicle that can transport barreled or canned goods. Since the canned goods need to be lifted in and out of the vehicle after opening the top cover, part of the top cover of the box car needs to be designed as a movable cover. [0003] The movable cover plate that existing railway wagon installs mainly contains many types of forms such as rotary (single opening, double opening), sliding type. The transmission system usually uses a rocker mechanism, and then the hydraulic cylinder drives the rocker to drive the movable cover to rotate or slide sideways to realize opening and closing. Some movable cover plates using electric transmission mechanism drive the driving rod through the transmission belt to realize the opening and closing of the flat top. ...

AI Technical Summary

Problems solved by technology

The mechanical structure of the hydraulic rocker mechanism is complex, and the hydraulic device will leak oil, which increases the probability of failure

The transmission structure of the electric rotating mechanism is complicated, the installation is cumbersome, and power supply needs to be provided to the vehicle, which is not easy to realize for the truck
